I am asking myself a question about the voltage that the injector takes when opening ... The voltage on the side + injector = 14V The voltage on the side - injector = voltage of the mos drain (peak at 80V when opening) So the injector ends up with a peak of -66V at these terminals (14V-80V). It does not risk ...

ok i will do like that.
Anyway I looked at your source code, I won't be able to do better, so I might as well take the hex directly

With which compiler did you write the code?

To all those who made the kit, did you make the PCB yourself?

Suddenly, I think going on the layout that you have done, I hope to have time to do this during January.

In terms of reliability, have you been using it since 2008? So it's proven.

Ok. In fact I intend to make an E85 kit, and I did not know if I would repeat your assembly and code but with a pic18F1220 or 1230 for example, because I have some and I am more used to pic18, and that this one is pin to pin compatible, just the code has to be adapted a little. I have MPLAB and the C18 compiler ....

Thank you for this additional information. Another point, the injector is an inductive element, when the mos is opened, this must create a fairly large overvoltage given that the current no longer has a "path" to flow. Would it be advantageous to add a free wheel diode in pa ...

Hello, I'm new to the forum, I am 24 years old and an electronic engineer. I like electronics, mechanics, and when I can link the 2 it's a treat :). Here is for the presentations. I watched carefully all the work done by NLC, it's a good job, and I ask myself a few questions ...
